Course content

The objective of the course is to transfer a basic understanding of fundamental properties and characteristics of quantum structures, and how these properties can be exploited for applications in photonics, electronics, and future quantum technologies. Within the frame of the course, a description of the important methods to fabricate, characterize and model epitaxial quantum structures. The course aims at an improved understanding of the effects caused by a reduction of the dimensionality of a semiconductor; from the 3-dimensional bulk, via 2- and 1-dimensional quantum wells and -wires, to 0-dimensional quantum dots.

 

    •    Methods for fabrication of epitaxial quantum heterostructures

    •    Defects in semiconductors, the effective mass model

    •    Models for energy bands and quantized energy levels in defects, quantum wells, wires and dots

    •    Internal strain and electric fields in heterostructures

    •    Distribution functions for electrons and holes, density of states and doping

    •    Transport properties and scattering processes in low-dimensional systems, including resonant tunneling, quantized conductance, and the quantized Hall effect

    •    Optical properties, absorption, and low-dimensional excitons

    •    Recombination processes, the Purcell effect and quantum electrodynamics

    •    Concepts for manipulation and measurement of individual electrons and photons

    •    Applications and potential applications of quantum structures

 

Laboratory Exercises

    •    Absorption and recombination in quantum structures with luminescence based spectroscopy

    •    Numerical approaches for modeling of quantized states and band structure

Teaching and working methods

Lectures, tutorial sessions and laboratory exercises. The tutorial sessions are mainly focused on problem solving, but can to some extent also include demonstration of research facilities. The laboratory exercises includes moderna approaches for characterization and modeling of quantum structures.
